51c7e6ac24 drm/amd/display: revert "for FPO & SubVP/DRR config program vmin/max"
This reverts commit 6b2b782ad6.

The original commit causes issues with certain features when DRR is
disabled, need to revisit this change later after resolving issues with
new DRR policy.

292c2116b2 drm/amd/display: Fixing stream allocation regression
For certain dual display configs that had one display using a 1080p
mode, the DPM level used to drive the configs regressed from DPM 0 to
DPM 3. This was caused by a missing check that should have only limited
the pipe segments on non-phantom pipes. This caused issues with detile
buffer allocation, which dissallow subvp from being used

09b5bc456c drm/amd/display: Assign stream status for FPO + Vactive cases
A new check was added to ensure FPO is not enabled when the FPO pipe has
0 planes. This requires the stream status to check the plane count, but
the stream status was not assigned for FPO + Vactive cases which leads
to FPO not be enabled always.

ade13d3fc0 drm/amd/display: Don't allow FPO if no planes
In DCN32/321 FPO uses per-pipe P-State force. If there is no plane, then
then HUBP is power gated, in which case any programming in HUBP has no
effect and the pipe is always asserting P-State allow. This is contrary
to what we want to happen for FPO (FW should moderate the P-State
assertion), so block FPO if there's no plane for the FPO pipe.

012a04b1d6 drm/amd/display: Refactor phantom resource allocation
[WHY?]
Phantom streams and planes were previously not referenced explcitly on creation.

[HOW?]
To reduce memory management complexity, add an additional phantom streams and planes
reference into dc_state, and move mall_stream_config to stream_status inside
the state to make it safe to modify in shallow copies. Also consildates any logic
that is affected by this change to dc_state.

dd2c5fac91 drm/amd/display: Add ODM check during pipe split/merge validation
[why]
When querying DML for a vlevel after pipes have been split or merged the
ODM policy would revert to a default policy, which could cause the query
to use the incorrect ODM status. In this case ODM 2to1 was validated,

vlevel.

- Also ensure to block drr + vblank cases to prevent unexpected
  enablement of new display configs
- Update SW cursor fallback for these new potential cases as well

7966f319c6 drm/amd/display: Introduce DML2
DC is transitioning from DML to DML2, and this commit introduces all the
required changes for some of the already available ASICs and adds the
required code infra to support new ASICs under DML2. DML2 is also a
generated code that provides better mode verification and programming
models for software/hardware, and it enables a better way to create
validation tools. This version is more like a middle step to the
complete transition to the DML2 version.

Changes since V1:
- Alex: Fix typos

Changes since V2:
- Update DC includes

Changes since V3:
- Fix 32 bit compilation issues on x86

Changes since V4:
- Avoid compilation of DML2 on some not supported 32-bit architecture
- Update commit message

5d72e247e5 drm/amd/display: switch DC over to the new DRM logging macros
For multi-GPU systems it is difficult to tell which GPU a particular
message is being printed for and that is undesirable because it
complicates debugging efforts. Also, the new macros allow us to enable
logging for particular parts of the codebase more selectively (since we
no longer need to throw everything at DRM_DEBUG_KMS()). So, for the
reasons outlined above we should switch to the new macros.

We can accomplish this by using the existing DC_LOGGER code to pass
around the relevant `struct drm_device` which will be fed to the new
macros in logger_types.h. Also, we must get rid of all instances of the
DC_LOG_.*() functions that are currently in amdgpu_dm since we don't use
the DC logger there and we can simply refer to the macros directly
there instead.

[why]
In some cases such as 8k desktop surface with 144Hz timing, we decide to
enable ODM power optimization but this surface doesn't have a minimum
transition state. Therefore we cannot switch off ODM power optimization seamlessly
This creates path depedency on ODM power optimization decision. i.e
whether or not we should switch off ODM power optimization is dependent
on if the transition to switch off ODM power optimization from current state
is seamless. We don't desire a path dependent power optimization policy
as it is too dynamic and difficult to maintain.

Attempt ODM power optimization only after we can validate new state without
using pipe combine.

07926ba8a4 drm/amd/display: Add debugfs interface for ODM combine info
[Why]
For use with IGT tests in userspace, the number of ODM segments in use
is required to be exposed to userspace to verify that ODM Combine is
working as expected when special timings are committed.

[How]
Add a connector specific debugfs entry that prints the number of ODM
segments in use.

b03b44b622 Partially revert "drm/amd/display: update add plane to context logic with a new algorithm"
This partially reverts commit 460ea89805 ("drm/amd/display: update add
plane to context logic with a new algorithm").

The new secondary pipe allocation logic triggers an issue with a
specific hardware state transition and causes a frame of corruption when
toggling between windowed MPO and ODM desktop only mode. Ideally hwss is
supposed to handle this scenario. We are temporarily reverting the logic
and investigate the root cause why this transition would cause
corruptions.

53f3288079 drm/amd/display: implement pipe type definition and adding accessors
[why]
There is a lack of encapsulation of pipe connection representation in pipe context.
This has caused many challenging bugs and coding errors with repeated
logic to identify the same pipe type.

[how]
Formally define pipe types and provide getters to identify a pipe type and
find a pipe based on specific requirements. Update existing logic in non dcn
specific files and dcn32 and future versions to use the new accessors.

198f0e8953 drm/amd/display: rename acquire_idle_pipe_for_layer to acquire_free_pipe_as_sec_dpp_pipe
[why]
Secondary DPP pipes are used for rendering secondary layers of planes.
The name "for layer" doesn't make it obvious. The function is acquiring
a free pipe as secondary dpp pipe only. We rename it so it is more obvious.
In a future follow up change, we want to add functions to acquire free pipe as
opp head pipe or otg master pipe as well. They will have their separate
allocation priority.

460ea89805 drm/amd/display: update add plane to context logic with a new algorithm
[why]
Preivous algorithm for finding an optimal idle pipe for a new plane was
implemented to handle dynamic pipe allocation when MPO plane moves
from one ODM slice to the other. Now pipe allocation is more static so
it no longer depends on the MPO plane's position. We are simplifying
our logic and remove unnecessary handling in our code.

[how]
Apply a new simplified version of pipe resource allocation logic to reduce
unnecessary flip delay caused by swapping secondary dpp pipe to other
MPC blending tree.
